Finding the lower and upper bounds of Hybrid model in DEA, in uncertainity environmens

This paper propose how to conduct efficiency assessment using data envelopment analysis (DEA) in interval environments by introducing two pairs of interval DEA models which the former is redial and the latter is non-redial consequently we find the upper and lower bound of interval efficiency of hybrid model in DEA which is the integration of redial and non-redial models.
